If you clench or grind your teeth at night, then you might wear night guards, which are preventive dentistry devices designed to protect your teeth. But could these devices be moving your teeth over time? According to Thomas F. Brown, DDS, a professional and properly fitted splint should not drastically or permanently change your bite, but certain factors could affect the harmony of your smile.
Replacing old mouth guards is one of the easiest and best ways to prevent unintended bite changes. So, if it’s time to replace your old splint, contact our Naperville, IL, dentists at (630) 296-9156 for a consultation now!
Why Some People Think Their Bite Is Changing
Some patients report that their bite feels “off” after wearing night guards. This sensation can be temporary and does not always mean the bite has truly changed.
There are a few reasons for this feeling:
- Jaw muscles relax during sleep
- The guard slightly separates the teeth overnight
- Morning stiffness affects how teeth come together
In many cases, your bite returns to normal shortly after removing the appliance.
When Bite Changes Can Actually Occur
Although uncommon, night guards can contribute to bite changes in certain situations.
Clinical research has documented cases where occlusal splints led to unintended changes in how teeth come together, including conditions like anterior open bite. This is considered a rare side effect and usually occurs under specific conditions, like long-term use without proper professional monitoring or not replacing old or damaged devices.
Factors That Increase the Risk of Bite Changes
Not all night guards are created equally. Certain factors can increase the likelihood of bite changes:
Poor Fit or Design
A splint that does not evenly contact all teeth can shift pressure unevenly. Over time, this may affect tooth position.
Partial Coverage Devices
Guards that only cover some teeth may allow others to move slightly. Full-coverage designs are generally safer.
Long-Term or Improper Use
Wearing night guards incorrectly or for extended periods without monitoring by Dr. Brown and his team can increase risk.
Lack of Dental Supervision
A dentist should regularly check the fit and function of your splint. If it’s been years since your last fit check, then it’s time to contact Dr. Brown for an evaluation.
Store-Bought vs. Custom Night Guards
Over-the-counter options may seem convenient, but they carry more risk. Boil-and-bite guards can fit unevenly and may not provide proper support.
However, custom night guards by Dr. Brown are designed specifically for your bite. This personalized approach helps maintain alignment and comfort.
What to Do If Your Bite Feels Different
If your bite feels off after using night guards, do not ignore it. Contact Dr. Brown for an evaluation. In many cases, a simple adjustment can resolve the issue. However, avoid trying to modify the guard yourself, as this can worsen the problem.
